This is a short example of taking a stochastic system, using Fokker-Planck to convert it to a PDES and using SUNDIALS to solve a 2D partial differential equation in Haskell via the hmatrix-sundials library. The example is taken from the C examples that come with the SUNDIALS source. Here’s the full blog.

Full disclosure: I'm a complete noob at making pizza. It's my second pizza, but hey, it was tasty and fun to make! Making pizza at home is not as far-fetched as I initially thought. UPDATES: I've made this recipe a couple of times. Made two improvements worth mentioning. Flan tin / quiche pan My first pizzas were rectangular, matching the baking tray shape, but I really wanted round pies. I found a quiche pan at home and gave that a ....

For the readers that might be unaware, Tekton is a cloud-native CI/CD solution. In other words, it’s a pipeline for Kubernetes that can generate DAGs (directed acyclic graph). It’s one of the most straightforward solutions to run dependent Pods and steps in Kubernetes. Tekton runs pipelines as Task CRDs (Custom Resource Definition), whereas every task can have one or more sequential steps. Also, a Task can have a dependency on another task,..

This is a post about how the Go compiler implements inlining and how this optimisation affects your Go code. n.b. This article focuses on gc, the de facto Go compiler from golang.org. The concepts discussed apply broadly to other Go compilers like gccgo and tinygo but may differ in implementation and efficacy. What is inlining? […]

Tmux has liberated me from tiling window mangers. Not that I didn’t like those, but I occasionally have to work with macOS or default GNOME setups. And over the years I realised that I only need a terminal multiplexor to do terminal tiling for me, the rest of the windows are just fine to be full-screen in separate workspaces. So, I ended up doing 80% of my work in terminals with tmux.

The Internet succeeded in no small part thanks to the humble hyperlink. The link enabled it to flourish as a network rather than languish as a series of closed silos, which led to its widespread adoption and the prevalence it enjoys today. Although a disturbing trend of centralization has emerged in recent years, many people have made great efforts to combat it; they may yet succeed. Their efforts have relied on the link to bring users toge..

License compliance is crucial for being able to minimize the risk to the business but the only way to do so at scale and without impeding development is with a developer-first mindset.

Modern computers have gotten so complex that the prospect of trying to understand them intimidates a lot of people. Unfortunately, many use that fear as an excuse not to even try. Nelson Elhage has some great advice for tackling this gargantuan task. Permalink.

In the world of software engineering, the term Bus Factor refers to the number of people on your team that have to get hit by a bus for your project to collapse: The bus factor is a measurement of the risk resulting from information and capabilities not being shared among team members, derived from the phrase "in case they get hit by a bus." It is also known as the bread truck scenario, lottery factor, truck factor, bus/truck number, ....

So as of about 12 hours a new version of https://searchcode.com/ has been rolled out. It marks the biggest update to the site in over 4 years since I moved over to version 3 which you can read about https://boyter.org/2016/07/searchcode-com-architecture-migration-3-0/ The reason for it was that searchcode has always been something I kept running as a showpiece. It’s something that I can point to publicly and say “I did that”. The idea..

One of my most fascinating work experiences was going through the spokesperson certification process at a large tech co. This isn’t some rubber stamp virtual training to not use profanity on stage type training. This is the training they would give to any executive before you were greenlit to talk to press. When I say press I mean Techcrunch, but also Bloomberg, or Jim Cramer, or any major big brand news outlet. As a product manager over ....

I’ve worked at four marketplace startups in my relatively short career. I do at least have enough experience on how I’ve seen successful (and unsuccessful) companies scale their engineering organizations for marketplaces. There is a unique problem of scale that only happens with marketplace startups and it is worth addressing as a post. If you are an engineering leader for a growing marketplace startup, here are a few tips to handle team gr..

I recently read a post on the habits of high-functioning teams with a great discussion over on HackerNews. One person, in particular, wondered if you could apply these concepts on to dysfunctional teams and turn them around. Since I’ve have the opportunity to turn around teams before I thought I would weigh in on this question with each habit.

The results show fingerprints are good enough to protect the average person’s privacy if they lose their phone. However, a person that is likely to be targeted by a well-funded and motivated actor should not..
